The big brother of the 1SKB-iSF2U! This case features a virtually indestructible, waterproof injection molded shell that is lighter, stronger, and more affordable than the previous 4U Studio Flyer, and includes innovative molded-in front and rear rack rails that provide even more security and durability for sensitive studio equipment during travel. As a larger Studio Flyer option, The 1SKB-iSF4U offers a 4U rack mount measuring 15″ from front rail to rear rail which safely accommodates deeper equipment, such as the Universal Audio Apollo audio interface. It also provides a 21″ x 15.5″ adjustable work surface with ample room for laptops or monitors, and a specially molded exterior pattern that stacks securely with all SKB Roto Racks for maximum transport convenience.

Other standard features include improved quiet-glide wheels, an easy-to-operate one-button pull handle, and TSA-accessible locking trigger latches. Like all SKB Injection Molded cases, the 1SKB-iSF4U is proudly made in the USA and comes with an Unconditional Lifetime Warranty.

CALIFORNIA WARNING: Cancer and Reproductive Harm -

California Proposition 65

You may have heard that everything gives you cancer – if you live in California. The reason is that it is a California state law that requires businesses to provide reasonable warning about the use of any chemicals the state has decided could cause cancer, birth defects, or other reproductive harm. The list of chemicals and substances is extensive - currently totaling approximately 900.

For those consumers who live outside of California, you are not accustomed to seeing Prop 65 Warnings everywhere you go to shop, eat, buy groceries, fix your car, and are even posted at amusement parks.

We have no reported cases of our products causing harm or danger to anyone. We believe in the safety of our products and we meet all the applicable safety requirements. We are unable to test against the 900+ chemicals listed for Prop 65 and to 100% certainty, and therefore, in an abundance of caution, we have placed the warning on our products to be in compliance with this California regulation. You will also see the Prop 65 warning on products that you buy outside of California, because we are unable to determine our products’ final retail destination.
For any questions you may have about our products and California Prop 65, please contact us.
